A user has launched an EC2 instance store-backed instance in the us-east-1a zone. The user created AMI #1 and copied it to the eu-west-1 region. After that, the user made a few updates to the application running in the us-east-1a zone. The user makes an AMI #2 after the changes. If the user launches a new instance in Europe from the AMI #1 copy, which statement is true?

Answer options:

A.The new instance will have the changes made after the AMI copy as AWS copies the original AMI reference during the copying. Thus, the copied AMI will have all the updated data.
B.The new instance will have the changes made after the AMI copy since AWS keeps updating the AMI.
C.It is not possible to copy the instance store-backed AMI from one region to another.
D.The new instance in the eu-west-1 region will not have the changes made after the AMI copy.

Answer – D
Option A is incorrect because (a) the changes made to the instance will not automatically get updated in the AMI in US-East-1, and (b) the already copied AMI will not have any reference to the AMI in the US-East-1 region.
Option B is incorrect because AWS does not automatically update the AMIs. It needs to be done manually.
Option C is incorrect because you can copy the instance store AMI between different regions.
Option D is CORRECT because the instance in the EU region will not make any changes after copying the AMI. You will need to copy the AMI#2 to eu-west-1 and then relaunch the instance to have all the changes.
